Yes it is. When you simplify the girls ratio( 12:30 by 6)you'll get 2:5. When you simplify the boys ratio( 16:40 by 8)you'll get 2:5. So it is the same ratio.

Nikitich [7]

Answer:

l = 100 / 8

Step-by-step explanation:

The standard formula for calculating area is bh = a.

Plug in 8 for our width.

8l = 100

Divide 8 on both sides.

l = 100 / 8.

Need help with a math question
Margaret [11]

Answer:

90 sq inches

Step-by-step explanation:

The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle.  Since the base is an equilateral triangle, all sides are of equal dimensions.  So, the sides of the pyramid are also all of the same size, area.

We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.

We know how to calculate the area of a triangle: A = (b * h)/2

In this case, b = 5 in, h = 12 in. So,

TA = (5 * 12)/2 = 60 / 2 = 30

Each side triangle has an area of 30 sq inches.

LA = 3 * TA (since there are 3 sides)

LA = 3 * 30 = 90 sq inches

A farmer has 64 feet of fence to enclose a rectangular vegetable garden. which dimensions would result in the biggest area for t
Blababa [14]
The dimensions that would result to maximum area will be found as follows:
let the length be x, the width will be 32-x
thus the area will be given by:
P(x)=x(32-x)=32x-x²
At maximum area:
dP'(x)=0
from the expression:
P'(x)=32-2x=0
solving for x
32=2x
x=16 inches
thus the dimensions that will result in maximum are is length=16 inches and width=16 inches
